Re-dose, leave alone, or cull?

[HeyyyChickens]

All my chickens received 1 cc of tylan 200 orally for 5 days. Their rattly breath, bubbly eyes, wet sneezes stopped and eventually with a new coop, I've moved them all over with a clean bill of health.

Except for one.

She does not have bubbly eyes, but they are not as sharp or bright as the others' healthy eyes.
She sneezes from time to time, but no mucus or vomit or discharge.

I am afraid of putting her with the healthy guys. I do not want to start a cycle all over again.

If she didn't sneeze, I wouldn't think twice and I would put her with the others. Is sneezing a couple times an hour enough of a reason to cull?

Do I try tylan 200 again, or is it going to be too much on her system? (The last dose was two weeks ago).

I culled two, so I'm not afraid of it, but there was something in my gut that didn't want to cull this one, but there's something in my gut that doesn't want to move her over either.

Advice? I'm stuck in limbo and she's now alone, isolated.

If you are thinking about culling her anyway, why not try the tylan again?

Yes, true, but don't know if I would shut her system down with more tylan since she just got off it 2 weeks ago??

Did you give it orally or injectable? What dosage did you use? I don't think tylan stays in the system very long, the withdrawal period on oral tylan is only one day.
